Three usual measurement methods(multiple activation technique
additive dose method and spine technique) for the pre- dose t6chnique .in thermoluminescence dating are discussed and the fine-grain quartz method has been described in detail. The results show that the fine-grain quartz method is not only sample
but also decreasing in errors of multiple activation
test dose and normalization. In addition
by using this method quite small ages(10-100year) are Possible to be accuratelyevaluated.
